Thoughts, stories and ideas from a Serial Tech Entrepreneur
The I.C.E. Battery represents a fundamental shift in how we approach cooling. By storing cold energy efficiently and delivering it passively, we can decouple cooling demand from peak energy generation, slash carbon emissions, and reduce operational costs.
Put simply, it's a thermal battery designed specifically to store "cold" energy at subzero -22°C or lower...
I want to offer a fresh perspective, a call for deeper self-awareness among founders and a more sophisticated approach to assessment for investors and co-founders.
🤯 An very unexpected Discovery
Full content of USPTO 12-130086-B1: Thermal Storage Batteries and Thermal Storage Battery Systems for Drying Agriculture and Food Products, aka the Sand Battery.
I want to take you back to where it all began - the earliest days of experimentation and collaboration that laid the foundation for what would eventually become a transformative energy storage solution.
We’ll design a simple setup with a full solar array to back up both systems, then evaluate multiple factors: cost, efficiency, lifespan, maintenance, and environmental impact. Let’s break it down!
We’ll explore a residential use case: supplying hot water for a homestay in a city with a climate averaging 15 – 20°C year-round.
First, exploring the zero-carbon-emission operation of the Sand Battery, and second, critically examining the "almost" part, where minimal emissions arise from auxiliary components and construction.
In my last 3-4 years, besides learning all the IoT tech stuff I can honestly say that my biggest breakthroughs had nothing to do with code or hardware. They had everything to do with “đối nhân xử thế” how we deal with people. How we survive them. How we survive
I’ll illustrate how the Sand Battery can save up to 50% or more of energy costs in a specific industrial use case, focusing on the calculation of thermal energy cost savings.
